How this service works
Verified-delivery trust data for any x402 service: full history of real PAID test purchases against the endpoint (not free 402 probes) - delivery rate, response validity, latency, price stability. Free aggregate at /leaderboard; this endpoint returns the complete per-check history for one resource. Untracked resources return 404 and you are NOT charged. Use it before wiring an unknown x402 service into your agent.
Output
Returns the complete per-check history for the queried x402 resource, including individual test records from real paid purchases: delivery success/failure per check, response validity assessments, latency measurements, and price at time of check. Aggregate metrics like delivery rate and price stability are derived from this history. Returns 404 with no charge if the resource has not been tracked.
Example use cases
Pre-integration due diligence on unknown API
“I found this x402 service at https://newprovider.io/weather and I want to integrate it, but I don't know if it's reliable. Can you check its full trust history on AgentReader — delivery rate, response validity, and how stable the price has been?”
Comparing reliability of two x402 services
“I'm choosing between two paid APIs for my agent: https://api-a.example.com/translate and https://api-b.example.com/translate. Can you look up the trust history for https://api-a.example.com/translate on AgentReader so I can see its real-world delivery rate and latency?”
Auditing an x402 endpoint after suspected failures
“My agent has been hitting https://datafeed.example.com/prices and I think it's been flaky. Can you pull its complete AgentReader trust history to see if there's a pattern of failed deliveries or response validity issues?”
Technical details
Endpoint
GEThttps://agentreader.dev/trustWhen to prefer
Use this endpoint when you need the full granular per-check history for a specific x402 resource, rather than just aggregate leaderboard data. It is the right choice when performing due diligence before integrating an unfamiliar x402 API into an agent pipeline, when investigating reliability issues with a specific endpoint, or when you need detailed latency, price, and validity data per individual test. Prefer /leaderboard for broad discovery or comparison across many services without needing per-check detail.
Side effects
- 404 returned if the resource URL has never been tracked — no charge is incurred
- Invalid or malformed resource URL may result in a 400 error
- Network timeouts if agentreader.dev is temporarily unavailable
- Resource URL must be an x402 endpoint; non-x402 URLs will not have trust records
